Characterizing the relationship between peak assistance torque and metabolic cost reduction during running with ankle exoskeletons

Table 2 Exoskeleton mechanics

Peak torque magnitude	Average work (J/kg)	Average mechanical power (W/kg)	Peak mechanical power (W/kg)
0.2 Nm/kg	0.10 ± 0.01	0.14 ± 0.01	1.75 ± 0.14
0.4 Nm/kg	0.23 ± 0.01	0.30 ± 0.01	3.79 ± 0.31
0.6 Nm/kg	0.35 ± 0.02	0.45 ± 0.02	5.82 ± 0.35
0.8 Nm/kg	0.46 ± 0.04	0.59 ± 0.03	7.77 ± 0.47

Average work, average mechanical power, and peak mechanical power increased with increasing peak torque magnitude
